Abstract

Gel transfersom merupakan sediaan semipadat yang mengandung vesikel transfersom dengan kemampuan meningkatkan penetrasi ke dalam kulit sehingga berpotensi digunakan sebagai sistem penghantaran transdermal. Penelitian ini bertujuan untuk merancang dan mengevaluasi stabilitas basis gel transfersom menggunakan fosfatidilkolin sebagai komponen pembentuk vesikel dan Tween 80 sebagai surfaktan untuk meningkatkan elastisitas vesikel. Penelitian ini difokuskan pada formulasi basis gel transfersom tanpa penambahan zat aktif, sehingga evaluasi dilakukan terhadap karakteristik fisik dan stabilitas sediaan. Karakterisasi awal meliputi uji organoleptik, pengukuran pH, viskositas, daya sebar, daya lekat, serta analisis ukuran partikel menggunakan Particle Size Analyzer (PSA). Seluruh parameter evaluasi dilakukan pada penyimpanan suhu 25 °C dan 40 °C selama 4 minggu. Selain itu, uji stabilitas dipercepat dilakukan hingga minggu ke-12 menggunakan climatic chamber pada suhu 40 °C ± 2 °C dan kelembapan relatif 75% ± 5%, dengan parameter yang diamati meliputi organoleptik, pH, dan ukuran partikel. Hasil pengamatan menunjukkan bahwa selama penyimpanan tidak terjadi perubahan warna, bentuk, maupun bau sediaan. Nilai pH berada pada rentang 6–7 dan masih sesuai dengan persyaratan Standar Nasional Indonesia (SNI). Ukuran partikel rata-rata dan indeks polidispersitas pada minggu ke-4 masing-masing sebesar 229,4 nm dan 0,687, kemudian menurun pada minggu ke-12 menjadi 172,2 nm dan 0,476. Tidak ditemukan adanya aglomerasi selama penyimpanan, yang menunjukkan kestabilan fisik sediaan yang baik. Secara keseluruhan, formulasi basis gel transfersom yang dihasilkan memenuhi persyaratan mutu fisik dan stabilitas, sehingga berpotensi untuk dikembangkan lebih lanjut sebagai sistem pembawa transdermal dengan penambahan zat aktif pada penelitian selanjutnya.

Abstract

Methyl cinnamate isolate is an aromatic ester compound with a conjugated chromophore system capable of absorbing UV-B radiation, making it a promising candidate for sunscreen formulations. This study aimed to determine the optimum concentration of methyl cinnamate isolate based on its sun protection factor (SPF) and to develop a sunscreen cream with satisfactory physical stability. Methyl cinnamate isolate solutions were prepared at concentrations of 1000, 2000, 3000, 4000, and 5000 ppm and screened for SPF activity. The concentration yielding the highest SPF value was incorporated into cream formulations containing different stearic acid concentrations as an emulsifier (F1: 8% w/w and F2: 10% w/w). The resulting formulations were assessed for SPF, physical characteristics during 28 days of storage at room temperature, microbiological quality, and methyl cinnamate content under accelerated stability conditions (40 ± 2°C and 75 ± 5% RH). The isolate at 5000 ppm (0.5%) exhibited the highest SPF value of 33.49, corresponding to the ultra-protection category. Both formulations maintained acceptable physical characteristics throughout the storage period. At day 28, SPF values were 13.87 for F1 and 17.02 for F2, with F2 remaining within the ultra-protection category. After three months of accelerated stability testing, methyl cinnamate content was 47.62% in F1 and 68.32% in F2. Microbiological evaluation also revealed contamination based on total plate count and yeast–mold count analyses. These findings indicate that methyl cinnamate isolate has potential as a sunscreen active ingredient; however, further formulation optimization and preservative incorporation are required to improve chemical stability and microbiological quality.

Abstract

Acne is one of the most common skin disorders affecting various age groups, particularly adolescents, and is caused by inflammation of the pilosebaceous follicles associated with bacterial proliferation. The primary bacteria involved in acne pathogenesis are Propionibacterium acnes (P. acnes) and Staphylococcus epidermidis (S. epidermidis). This study aimed to formulate an anti-acne gel containing ethanol extract of black mulberry (Morus nigra L.) fruit and to evaluate its antibacterial activity. The black mulberry fruit was extracted by maceration using 96% ethanol. The resulting extract was formulated into a Carbopol 940-based gel at three different concentrations: 1.25% (F1), 2.5% (F2), and 5% (F3). The formulated gels were evaluated for organoleptic properties, homogeneity, pH, viscosity, spreadability, antibacterial activity using the agar well diffusion method, and skin irritation using the Draize method. The results showed that the ethanol extract of black mulberry fruit exhibited antibacterial activity against P. acnes and S. epidermidis, with inhibition zone diameters of 12.0 ± 0.90 mm and 12.8 ± 0.59 mm, respectively, at a concentration of 1.25%, indicating strong antibacterial activity. After formulation into a gel, the highest antibacterial activity was observed in Formula 3 (F3) after 28 days of storage, with inhibition zone diameters of 15.1 ± 0.06 mm against P. acnes and 15.3 ± 0.10 mm against S. epidermidis. All formulations met the required physical evaluation parameters and showed no signs of irritation in a preliminary Draize irritation test during the observation period. Therefore, the ethanol extract of black mulberry fruit has the potential to be developed as a topical anti-acne gel with antibacterial activity against P. acnes and S. epidermidis.
